摘要： Carboxy substituted aromatic chromophores are reactively linked to fibers containing alcoholic hydroxyl groups, amino groups or thiol groups, such as cellulosic fibers, with the linkage produced in the presence of a cyanamide compound, such as cyanamide or dicyandiamide.

摘要： A novel class of dyes are disclosed of the formula: ##STR1## where D represents a chromophore and R represents a phosphonic or a phosphoric group. These acid groups serve both as water-solubilizing and as reactive groups to bond the dyes covalently to cellulosic substrates.
